To all whom it may concern: Be it known that I, GEORGE P. BUMP, citizenof the United States, residing at La Urosse, Wisconsin, have inventedcertain new and useful Improvements in Machines for Fastening Paper orlike Sheets Together, of which the following is a specification.

The invention relates to a machine for fastener or tie disclosed inLetters, Patent of the United States No. 1,009,644, dated November 91,1911. My present invention isanimprovement upon. that form of machinedisclosed in Let- United States No. 1,065,903, dated June 24:, 1913, anexample of such type of machine being illustrated 1n Letters Patent ofthe United States, No. 966,598, datedAugust '9, 1910, granted to R. B.Reasoner, myobject being to increase of the tool, reduce it to a minimumsize or convenient handling, and to simplify and reduce thecost ofmanufacture.

The tool comprises generall two jaws, one carrying a die or shear p ateand the other carrying a punch or cutter to cut a tongue from the sheetsof paper which are to befastened together, said cutter operating inconjunction with the shear plate to form this tongue. Associated withthe tongue and a needle, which move slit in thepaper and having aneye-into which the folder forces the end of the that as the needleretracts through. the slit in the superimposed sheets, it will'draw thetongue therethrough and thus complete the fastening together of thesheets.

In the drawings Figure 1 isa side view of the complete tool; Fig. 2 is apart sec. tional view and elevation, the part shown in section being thelower handle with its housing; Fig. 3 is a sectional view of the upperhandle with all the working parts connected therewith, the lower handlewith its housing being removed; Fig. 4 is a side view of'the Fig. 4 isabottom plan view ofthe lower handle member andahousing; Fig. 1 is anend elevation *of I the lower handle member and housing look Fig. 7 isa, plan-view of the stripper. plate; Fig. .8 is a plan view of the shearplate; Fig. 9 is a. side elevation of the upperjaw; 10 is an'end view ofsaid upper jaw; Figs. 11

In these drawings, 1 is a shear plate and 2 .the stripper plate whichreceive between them the sheets of paperwhich are to be fastenedtogether, 3 is the tongue cutter or punch, 1 the needle, and-5 thetongue tucker or folder. The shear plate or die is carried by a lowerjaw6. This jaw may be con-' 14 is a'bottom plan viewof Fig.

in the particular form shown it is secured to a lower handle member 7 byscrews 8, 9, a pair of said screws being oneach side of the tool, aswill be hereinafter described. The stripper plate 2 is secured at itsrear end by a screw 10 to the shear plate, and this stripper plate isformed of spring metal the tendency of which is-to close down upon theshear plate, it being normally held up by means, hereinafter described:

The punch or'tongue cutter 3, needle 4, and tucker or folder 5 aremounted ,u'pon an upper jaw ll, as will be hereinafter described. Thisupperjaw has-a pin and slot connection at 1 2 with. an upperhandle lever13, which latter. is pivotally connected with the lower jaw- 6 by thescrews 8. The upper and lower jaws jar-e further connected to-' getherbya pairof links 14. pivoted to the upper-jaw at 15, and having a pin andslot connection at16 with the lower jaw. The links arepivoted at 17 tothe upper handle lever.

A spring 18 attached atone end to the upper jaw at 19 and at its otherend to the pin 12 of the upper hand lever holds the nartsnormally in theposition shown in Fig. 2. withthe jaws "separated and the stripperplateraised ready to receive the paper sheets which are 'to be united. Theimmediate means for lifting the stripper plate may assume various forms,but'in the particular construction shown as exemplifying my infrom thestripper plate and having their 'upper curved ends restingon the ends.of. the links 14. These arms extend up across the spacebetween the jawsand are operated from the movement of the upper jaw. As the ipper handlelever is moved down to cause the punch tocii't out the tongue from thepaper, the needle,.t0 form the slit, and the tucker to turn the tongueto enter the eye of the needle; or slitter, thespring strip-- 'per'platewill move toward the shear plate.

at i'the'sa'me s ed' that the punch, tucker and needlea Vance to operateupon the paper sheets, orin other words at the same speed of closingmovementof thejaws, and

- because the stripper plate is arranged in a slightly lowerplane thanthe: lower ends off -'said parts just mentioned, said stripper platewill engage and securely hold the paper sheets before the punch tuckerand needle operate thereon, the stripper plate now re-. mainin'gfat restwhile the further closing of the jaws proceeds and the punch, tucker andneedleare 'operatingto make the tie; B

thus firmly clamping the paper sheets in a vance of the action of thetie formingele' ments thereon, a smooth clean tongue will befcut whichwill'work equally well in fine as well as the heavier grades of paper,as

all Lbuekling of" the paper sheets is prevented. S {"The flower handlemember is provided with a housing 21' and in the particular form I shownthis is an integral extension ofthe'" handle membe'r. Thishousing'receives'the upper handle, and all the working. parts shown in Fig. 3,including the upper handle. and all these working parts can. be removedfrom the housing as one body,,this groupof v mechanism being shown'inFig. 3. This re moval can be 'eflected simply by removing the screws 8and 9. I The-lower'handle member has no movement relative to the lowerjaw they being fixed together or in effect integral with each other,the-upper handle being the only one to have pivotal movement in relationto'the jaws. The lower handle, together with the" lower jaw and thehousing, may be said to bethe stationary portionof the tool, and thatthe upper handle, by movingdownvin relation to this fixed portion,causes'tlie upper jaw to closejupon the lower jaw, and.

' it will be observed that the movement of the sembled with the lowerhandle and its housing, this mechanism; is protected and concealedfromview,asshown in Fig. 1. The lower portion of the upper handle fitswithin this housing-also, i.

I prefer to form} the up or handle member and the lower handle wlthitshousing by stamping each of these arts from a single piece ofsheetmetal. 'I he housingwill be provided secured by screws 23 to ears 24bent in from the upper edges of the housing. This stamping for the-lower handle. and housing,- as shown in- Fig. 4',"is provided 'withcars 25 having elongatedopenings 26 throu h which the screws 9 p'assforholding t e lower-jaw 6"to the handle 7 and permitting it'sadju s'tment,for which purpose also the lower jaw'ha's elongated-openings, asat 27,

serve alsotojconnect the lower handle mem- "b'er,'lower jaw,'and upperhandle together.

The openings-for these screws are located in "the 'lowe'rhandle member,as at 28.

with a cover-portion '22 which is v "receiving'the screws 8 which formthe pivot connectior'r'ofE-the upper handle-member and standing side andend walls. It is provided with an opening 29 inits bottom wall. Thislower jaw is 'of less width at its rear portion, asfshown in Figpfi at30, to accommodate the'-links',14"which lie outside of,the jaw-sand'within'the'depending sides of the upper"handle ."-To the wider partof the lowerjaw th'edepending sides of the upper handle are pivoted. Theshear plate 1 is held to th'eglower jaw by screws 31. The shearplaterests upon the upper edges of the end and'side walls of/the lower jaw,and it "is narrowed at its rear portion to accommodate-the'lower endsiofthe upper handle member and the links 14-. The spring stripper plate issecured at its rear end by the screw 10 and nut 32, the screw passingthrough the shearplate and the nut fitting between the side walls of thelower jaw to prevent turning. This stripper plate has an opening 33through which the punch 3 and tucker '5.pass,, and an opening 34 throughwhich the needle or slitter 4 passes. It also has an upstanding stud 'orlip at the rear edgeof the opening 33 for retracting the tucker orfolder when raised,'as in Fig. 3, and for retaining it in this position.

"While the. control of this spring stripper plate may be eflect'ed invarious ways, I prefer as in the particular form shown to form it with'two'integral arms 20 cut from the rear portionof the plate, and bent uptherefrom with their upper ends suitably formed to engage and be liftedby a member or members moving with the upper jaw, which, inthepresntinstance, I have shown as the up er ends-of the, links 14. Thestripper; plhte, Wh'enlifted, is arrested by coming against the loweredges of the housing, the arresting bearing being preferably throughoutthe length of these edges and? the e ge of-the endwall of the housing.It; -will 'be observed in Figs. 1 and 3 that the stripper plate isparallel with the shear: plate. This relation is substantiallyvmainminedin.-both the open and closed positions; oft-he plates. In the openposition it facili-Q tates ready insertion of the paper sheets, and in:the closed position it insures the firm; holding or clamping of theaper through-{ out; the insertedportion of tie aper sheets whilethe tieis being formed. By utilizing the housing as the stop for arresting thelifting of the stripper plate, the space be- ,tween the stripper plateand the shear plate may be left free and unobstructed for the insertionof the paper sheets for a considerahle'idistance.

zlit will be observed that the lifting exerted throughthearms 20 isapplie force about midway of the length of the stripper plate, andAli-is .aids'in the maintenance of the.

parallelism'justmentioned, and another re- ;sult ofithe arrangement isthat the lifting arms are concealed and protected by the housing. Theselifting arms embrace the upper jaw 11. This upper jaw is a sheet metalstamping having a topwall and side walls, It is located at its rearportion within the depending sides of the upperhandle and at its frontportion within the housing 21,

dying close to the upper wall of said housing .when in its normal openposition, as shown :lIl Fig. 2. It is concealed and protected by thehousing and upper handle.

lllhe punch-0r tongue cutterB is'stamped sup out or sheetimetal withsides inclined in .respect to each other to --c u-t a \V-.shaped tongue.Within-thispunch:the working end -of-the tucker5 is locateu, tsaidtucker, in the i particular form of -,-my iinvention .shown herein,being of spring metal, its upper end being turned downwardly, forwardly,andupwardly, ,providing a straight base portion having integral sidelugs '36 fitting between the adjacentedges of t 1e tongue cutter and theshankqoftthe needle-d. These side lugs are confined between projections37, 38, .forming integral parts .of the :tongue cutter and needleshank,respectively. The upper end of {theattaching or=ba-se portion of ;thetuckerisiprovided with a notch at38-which -receives the upper bend {ofthe metal strip {from which the gtucker is :formed. The tucker movesdown with the upper -j aw, and hence its lower end rides-off of itheprojection or .stud 85 .and moves 'to the right to fold the paper,tongue out by the :punch .3 into the eye of the needle, .thisimovementbeingv due to the spring of the metal of which the tucker is composed.When the jaws separate,the tucker rides on theiprojec- -tion 35. and itswork end moves alef-tward to the position shown in ,F ig. 3:Theseimovemeats under ieonstant use will .produce crystallization of themetal and consequent breakage were certain constructions of sprlngtuckers employed, but'with the form shown a long spring strip isprovided, the bend at the top being gradual and this merging into a,free downwardly extending portion,

which connects by a gradual curve with the upwardly extendlng base orattaching portion. The spring actlon is thus distributed over a springmember of considerable length g instead of being. confined to some onepoint or bend, and as aresult of this new construction the life of thetucker is greatly increased. The needle or paper slitter d is alsoformed by stamping it up. It is provided with integral flanges 39forming, with the main part of the needle, a shank, the edges of which,as above described, aline with the edges of the attaching portion of thetongue cutter, and being provided with the lugs 38, hold the tucker orfolder in conjunction with said tongue cutter.

The dengue cutter or punch 3 and the needle or slitter -it are heldwithin the upper jaw by a pair of pins 40 passing through notches il inthe front edge of the punch. and bearing in the side walls of the jaw,and by a pair of pins 42 hearing in the side walls of the upper jaw anda Wedge .43 interposed.

between the pins and the back face of the (an shank of the needle.

The'links 1d are stamped out of sheet metal with hollow journals 44upset. from the-metal ofthe links, these journals extending outwardlyand bearing in openings in a ea the sides of the upper'handle member.This construction avoids the .use of pivot pins, liableito drop out.

The upper handle is formed by stamping dies, and is all in one piece.llt is slidab-ly (the connected to the upper jaw and pivotally connectedby its extensions to the other jaw. It forms the fulcrum for the linkconnection, and in effect forms one member of said connection betweenthe jaws, providing with use the links 14 a. crossed link connection.

:Both of the handles are provided with guard projections 40',these'being curved to afford comfortable bearings for the hand.

They prevent the hand from slipping too M5 far forward.

While I have referred to the member4 as a needle, itwill be understoodthat this may be otherwise constructed than with an .eye,

so long as it performs the functions of makaec ing the slit and drawingthe end of the paper tongue up therethrough.

W here I have spoken of a shear plate or die on the lower jaw it will beunderstood that I do not limit myself to such plate or Mb tongue cuttingand folding means on one 160 connected with the jaws one of said handlesand jaws being connected rigidly and a link connection between the jaws,substantially as described.
